GENERAL INFORMATION

Use Restrictions

DO NOT USE IN FOODIFEED AREAS OF FOOD HANDLING ESTABLISHMENTS. Use in all permitted sites, including food handling establishments, must be restricted to structural voids which eliminate exposure to food handling surfaces, living areas, or to any occupants.

Do not apply this product in a way that will contact any other person. Only protected applicators may be in the area during application. Keep people or pets away from treated area until dry.

Prior to treatment, the applicator must check the area to be treated and the areas immediately adjacent to the structure for visible and accessible cracks and holes to prevent any leaks or significant exposures to persons occupying the structure. If spillage or leakage occurs, people present or residing in the structure during application must be advised to remove their pets and themselves from the area. After application, the applicator is required to check for leaks. All leaks resulting in the deposition of termiticide in locations other than those prescribed on this label must be cleaned up prior to leaving the application site. Do not allow people or pets to contact contaminated areas or to reoccupy contaminated areas of the structure until the clean up is completed.

Locate heating/air conditioning ducts, air vents, plumbing pipes, drainage systems, sewer lines and electrical lines/conduits before proceeding with application. Caution must be taken to avoid puncturing and contaminating these elements.

Do not apply Optigard ZT on open or exposed surfaces accessible to people or pets.

Do not apply until location of heat pipes, ducts, water and sewer lines, and electrical conduits are known and identified. Caution must be taken to avoid puncturing and injection into these structural elements. Do not apply into electrical switches or receptacles or other wiring where electrical shock hazards exist.

Application holes in living areas must be sealed after treatment. -6- {Label language for all Optigard ZT labels}

GENERAL APPLICATION INFORMATION

General Procedures

Optigard ZT must be applied as a diluted finished application using mixing directions contained in this label, and applied in a manner so that exposure to surfaces in living spaces (such as the living area sides of walls, floors, ceilings, countertops, or other surfaces) is eliminated. Applications must be restricted to areas that are not accessible to occupants of the structure and are not open to living spaces. Treatment techniques used should provide placement of the diluted product as near the infested areas as possible. Application to structural voids such as wall voids should be done by drilling a small hole into the void area or using a self-puncturing tip and injecting diluted product so that surfaces inside the void area are treated.

Do not apply to the surface of walls, ceilings, decorative timbers, or floors accessible to occupants of the structure. -7- {Non-Unit Dose /abe//anguage}

As described in the section on CONTROL OF ARTHROPODS THAT ARE OCCASIONAL INVADERS IN STRUCTURAL VOIDS, closed, in-wall delivery systems may be used as described to apply product to the surfaces inside void areas.

MIXING PROCEDURES

Dilution Rates

For drywood termite control, use a 0.1 % dilution. For other pests on this label, 0.025- 0.1% dilutions may be used, depending on pest pressure and desired service interval.

Mixing

Refer to Application Dilution Table for proper amount of Optigard ZT to be used. To prepare the application mixture, fill the application tank 1/4 - 113 of desired volume with water before adding Optigard ZT. Then slowly add the required amount of Optigard ZT. Add the remaining amount of water and agitate until product is thoroughly mixed.

DRYWOOD TERMITE CONTROL

When used as recommended in this label, Optigard ZT provides effective remedial control of localized infestations of drywood termites, including species of /ncisitermes, Cryptotermes and Marginitermes. Knowledge of the biology and behavior of the drywood termite species involved, and the extent of the infestation will help to ensure successful control.

Treatment requirements for drywood termite control may vary due to state and local regulations. For advice concerning current drywood termite control regulations under local conditions, consult your State structural pest control regulatory agency.

Optigard ZT has not been approved for application to soil for control of subterranean termites.

DIRECTIONS FOR REMEDIAL CONTROL OF DRYWOOD TERMITES IN INFESTED WOOD

To control drywood termites in localized areas of infested wood in structures, apply 0.1 % Optigard ZT as a liquid or foam to voids and galleries in damaged wood, in spaces between wooden structural members or between wood and foundations. Locate galleries by using visual signs (e.g. fresh fecal pellets, or blistered wood), the presence of live pests, mechanical sounding techniques (tapping on the wood surface and listening for changes in sound to indicate changes in wood density), listening devices, motion detection devices or other technology that helps pinpoint drywood termite activity. -9- {Non-Unit Dose label language}

Wood Injection Method

Drill small diameter holes of appropriate size for the injection tip or use a self-puncturing tip positioned to intersect termite galleries within infested wood. Drywood termite emergence or pellet kick-out holes connect directly to galleries and are indicators of potential sites to drill and inject Optigard ZT. Care should be taken to avoid electrical wiring, plumbing, etc., when drilling and injecting. Do not drill or puncture completely through wood. Spacing of the holes will depend on the distribution of insect activity and galleries. Injection holes may be clustered in areas with insect activity as indicated by damage, live insects, or other indicators previously described. Injection holes on opposite sides of large (4"x10" or larger) structural beams may be necessary to effectively penetrate galleries.

Apply up to 50 ml. (1.7 oz.) of finished Optigard ZT solution at each injection hole. It is not necessary to inject Optigard ZT until runoff is detected from other holes. Holes must be plugged after treatment. Use inert materials such as a wooden dowel, wood putty or a touch up stick for wood surfaces to minimize the possible disturbance of termites from entry of fresh air into galleries.

Re-treatment guidelines: Reapply if insect activity within treated areas is detected 4 or more weeks following treatment. For best results in treating galleries, inject Optigard ZT into new injection holes positioned between previous injection sites.

CONTROL OF ARTHROPODS THAT ARE OCCASIONAL INVADERS IN STRUCTURAL VOIDS

Arthropod pests may occasionally invade structures through wall voids or other structural voids by entering cracks or other openings to the exterior. In conjunction with other appropriate methods such as exclusion or perimeter insecticide applications, Optigard ZT can control nuisance arthropods that move through or are harbored in wall void areas.

Method of Injection into Wall Voids

To control certain (listed) nuisance arthropod pests, apply Optigard ZT Insecticide at 0.025%-0.1% finished solution/foam to surfaces inside structural voids. Application to structural voids such as wall voids should be done by drilling a small hole into the void area or using a self-puncturing tip and injecting product as liquid or foam so that wood surfaces inside the void area are treated. Existing openings such as those around door or window frames may be used to inject product, provided these openings are sealed after treatment. Apply enough volume to lightly coat the target surface. Do not exceed liquid volume that would allow runoff (e.g. for wood, runoff is about 0.05-0.1 mL.lsq. inch). For example, a 2x4 wall void with wood frame should be treated with 2-4 ml. finished solution per linear foot; other surfaces or wall void sizes may need more or less to achieve a light coating. For foam preparations, see instructions for use provided in -10- {Non-Unit Dose label language} the MIXING PROCEDURES section of this label. All injection points must be sealed with a suitable sealant material, such as caulking. Alternatively, closed, in-wall delivery systems may be used as described below to apply product to the surfaces inside void areas (see specific instructions in next section). Care should be taken to avoid application to any unenclosed areas.

Fixed In-Wall Delivery System~

Closed, in-wall insecticidal delivery systems such as permanently installed piping or flexible tubing may also be used to deliver diluted product to inaccessible areas. Generally, about one ounce of finished product is needed per 35-40 ft. of tubing (based on '/en-diameter tubes). For these systems, use 0.025%-0.1 % dilution rates as listed in the Application Dilution Table. Prepare the finished product at the appropriate dilution, inject into system as recommended by delivery system manufacturer.

Recommendations for Applications to Structural Void

When applied as directed, the following pests will be controlled with Optigard ZT:

Dosage of Optigard ZT Target Pests Insecticide Remarks

Ants 0.025-0.1% Use 0.05% - 0.1 % rates for Beetles heavy pest infestations. Boxelder Bugs (0.14 fl. oz. [4 mL.]- 0.54 fl. Also, rate used may be Centipedes oz. [16 mL.] Optigard ZT based on the residual Crickets Igal. water) control or service period Earwigs desired. (e.g. for quarterly Firebrats service, use 0.025% Millipedes dilution, 0.05% for 6 month Pillbugs service and 0.1% for single Silverfish application or longer Sowbugs service periods.)

Need for re-treatment should be based upon results of monitoring for pest presence. Do not apply more than 4 times per year.

CONTROL OF CARPENTER ANTS

For control of carpenter ants in structures, apply a 0.05%-0.1 % finished solution as a wall void application or to infested wood portions of structures. Void areas may also be treated using foam. Apply through small holes drilled into voids or using a self puncturing tip where these ants or their nests are present. EXisting openings such as those around door or window frames may be used to inject product, provided these -11- ,If,s {Non-Unit Dose /abe//anguage} openings are sealed after treatment. Base need for re-treatment upon results of monitoring for pest presence.
